23 Claims. (Cl. 72-127) This invention relates to flashing of the kind Fig. 3 is a fragmentary view of a bent portion shown and described in my United States Patof a flashing embodying my invention, showing ent No. 1,935,116 of Nov. 14, 1933, and has for its in detail the intersecting longitudinal and'transobject to provide certain improvements in the versely extending wicks and the clip means for construction therein disclosed. securing the wicks to the flashing at the point According to my prior patent, the flashing is of intersection; formed from a sheet of waterproof material, such Fig. 4 is a fragmentary View illustrating a as sheet copper, bent lengthwise to form flanges modified form of the flashing shown in Fig. 1, or other shapes, depending upon the position intended particularly for use in window heads which it is to-occupy in the wall of a building and and sills, and in which a transverse weep hole is having rope-like wicks, composed of cotton or provided by means of a rolled edge of the flashother material which will gradually deteriorate, ing strip, the inner side of which is apertured to particularly under the action of moisture, secured receive and hold an end of a longitudinally exto the flashing strip to extend transversely theretending weep hole forming wick;

Within any desired Fig. 2 is a transverse section through a wall of number of these flat portions 8 and 9 may be a bu d showing the flashing ooked in the secured rope-like wicks 10 and 11. These wicks morta a d th IOHgitlldinal W p es W i may be formed of soft rolled cotton and secured are formed in the mortar by the wicks carried to the flashing strip by means of metal clips as 55 by the flashing; 1 shown and described in-my prior patent. I have found it desirable, however, to employ clips of the form shown in Fig. 3, at the points of intersection of the longitudinally and transversely extending wicks.

As shown, the clip comprises a substantially rectangular piece of sheet metal struck from one side to provide ribs 12 extending from corner to corner and which intersect at the center of the clip, leaving triangular flat portions 13 between the right-angularly extending ribs which may be soldered or spot welded to the face of the flashing strip.

While I have explained that additional clips or anchors 13 of the types shown in my prior patent may be employed to securely fasten the wicks to the upper surface of the flashing strip 5, and extend between the bricks of an adjacent course to securely anchor the flashing to the wall, I have found that such anchoring means 13 may be employed with excellent results when secured to the under side of the flashing, as shown in Figs. 2 and 5. It will be understood, of course, that when such corrugated clips l3 are secured to the under surface of the flashing they function solely as anchoring means for the strip, in the manner explained in my prior patent.

As shown in Figs. 1 and 2, two longitudinally extending wicks l0 and 10 are shown secured to each horizontal step portion of the flashing strip 5. It will be seen that the formation of ribs into groups not only provides bend lines for the strip, but also trough portions at and intermediate the bends in which one or more wicks may be secured to meet the requirements of the particular job.

In Fig. 4 I have shown a transverse edge 14 of the flashing strip 5 rolled over upon the upper face of the strip to provide a weep hole conduit 15 which extends throughout the width of the strip. This form of flashing has been found desirable when relatively short lengths are required, as, for instance, in flashing window heads and sills. It will be understood that when so used, both ends of the flashing are rolled in the manner illustrated in Fig. 4 and one or more wicks 10 secured to the flashing-strip to extend longitudinally thereof. To provide continuous communication between the longitudinally extending wicks 10 and the transversely extending conduits 15, the rolled portions 14 of the sheet are apertured at 16 to receive and retain the end portions of the wicks as is clearly shown in Fig. 4.

As shown in Figs. 5 and 6, I may also make use of the form of flashing illustrated in Fig. 4 in a wall construction of considerable length. In such cases one end of each flashing strip 5 is rolled inwardly upon the upper face of the strip as indicated at 14 in Fig. 4 and the opposite end of the strip is rolled outwardly as indicated at 17 in Fig. 5 to embrace and interlock with the rolled edge 14 of an adjacent strip. It will be apparent from the foregoing that in orderto obtain the advantages of the construction shown in Fig. 4 when adjacent sheets are interlocked as shown in Fig. 5, that both sides of the rolled portions 14 and 17 are apertured as at.l6 in Fig. 4 to receive and retain end portions of wicks 10.

While the integrally formed conduits 15 shown in Figs. 4 and 5 are intended to take the place of the transversely extending weep hole forming wicks 11 in certain installations it will be understood that the wicks 11 may be used in any number desired in combination'with the integrally formed conduits 15 and longitudinally extending wicks 1010 to effect rapid drainage of water from the interior of a wall to the exterior thereof (see Fig. 5) and provide means for the continuous circulation of air through the wall adjacent the upper surface of the flashing and to the furring spaces 18 behind the walls.

While I have described and shown but a few embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement of the ribs and weep holes forming means may be made which do not depart from the spirit and scope of the invention as described in the appended claims.
